Data Tables

One way to collect data is to collect it in a data table.

Data collectors usually use tally tables to collect information.

To make it easier to read, usually data collectors use a cross tick for every fifth tally.

Column Graphs

This is a side column graph.

Column graphs use bars to represent data.


Data can also be represented using Pictographs.

Pictographs use pictures to represent information.

Sometimes each picture doesn’t have to represent 1 item. In this case each paw print represents 2 votes. So there are 8 votes for cats, 4 votes for dogs and 6 votes for hamsters.

Dot Plots

Dot plots are similar to pictographs but using dots instead of pictures to represent data.
